The Delete Overlay (DLTOVL) command deletes an overlay from the specified library. If the overlay is found, it is deleted. If the overlay is not found, a message is sent to the user stating that the overlay could not be found.

Parameters

Keyword	Description	Choices	Notes
OVL	Overlay	Qualified object name	Required, Positional 1
	Qualifier 1: Overlay	Generic name, name
	Qualifier 2: Library	Name, *LIBL, *CURLIB, *USRLIBL, *ALL, *ALLUSR

Overlay (OVL)

Specifies the overlay to delete. A specific overlay or a generic overlay can be specified.

This is a required parameter.

Qualifier 1: Overlay

generic-name

Specify the generic name of the overlays to delete. A generic name is a character string that contains one or more characters followed by an asterisk (*). If a generic name is specified, then all overlays that have names with the same prefix as the generic overlay name are deleted.

name

Specify the name of the overlay to delete.

Qualifier 2: Library

*LIBL

All libraries in the library list for the current thread are searched until the first match is found.

*CURLIB

The current library for the job is searched for overlays to delete. If no library is specified as the current library for the job, QGPL is used.

*USRLIBL

If a current library entry exists in the library list for the current thread, the current library and the libraries in the user portion of the library list are searched. If there is no current library entry, only the libraries in the user portion of the library list are searched.

*ALL

All libraries in the system, including QSYS, are searched.

*ALLUSR

All user libraries are searched. All libraries with names that do not begin with the letter Q are searched except for the following:

#CGULIB     #DSULIB     #SEULIB
#COBLIB     #RPGLIB
#DFULIB     #SDALIB

Although the following Qxxx libraries are provided by IBM, they typically contain user data that changes frequently. Therefore, these libraries are considered user libraries and are also searched:

QDSNX       QRCLxxxxx   QUSRIJS     QUSRVxRxMx
QGPL        QSRVAGT     QUSRINFSKR
QGPL38      QSYS2       QUSRNOTES
QMGTC       QSYS2xxxxx  QUSROND
QMGTC2      QS36F       QUSRPOSGS
QMPGDATA    QUSER38     QUSRPOSSA
QMQMDATA    QUSRADSM    QUSRPYMSVR
QMQMPROC    QUSRBRM     QUSRRDARS
QPFRDATA    QUSRDIRCL   QUSRSYS
QRCL        QUSRDIRDB   QUSRVI

1. 'xxxxx' is the number of a primary auxiliary storage pool (ASP).
2. A different library name, in the format QUSRVxRxMx, can be created by the user for each previous release supported by IBM to contain any user commands to be compiled in a CL program for the previous release. For the QUSRVxRxMx user library, VxRxMx is the version, release, and modification level of a previous release that IBM continues to support.

name

Specify a library name. Only the library named in this parameter is searched for overlays to delete.

Examples

Example 1: Deleting Overlays in All Libraries

DLTOVL   OVL(*ALL/OVL1)

This command deletes all the overlays named OVL1 in all the libraries, including all IBM-supplied libraries.

Example 2: Deleting Overlays in Current Library

DLTOVL   OVL(*CURLIB/OV*)

This command deletes all the overlays that begin with the letters 'OV' in the current library.

Error messages

None
